Wording is funky. To clarify:
The rain smell is due to a compound called geosmin. The bacteria that produces it is Streptomyces.
When I taught microbiology lab, I would grow a petri dish of Streptomyces during one particular class and have the students smell it
You mean… You can … Bottle up petrichore ??? How come is there no wide range of perfume/candle/lotion and whatnot?
Can I make it at home, if so, how would I go about it with everyday items? Can stretomyces cause health issues?
There absolutely are petrichor scented things
There’s like an indian family/company that’s been making some hiqh quality petrichor perfume for idk at least 100 years, probably several hundreds, if not a thousand or more idk.
I forget what it’s called you can probably look it up with perfume pertrichor india
Yup. I have a shaving soap like that called “Summer Storm.”
I’ve never smelled the stuff but apparently the smell of rain is something people try to bottle.
Well the smell of rain is actually petrichor, it just has a combination of geosmin and ozone and other chemicals that make that smell.
Geosmin on its own is just a part of it.

Why would we need such a strong sensitivity to it?
We evolved in the Savannah.
Rain means the watering holes are filling up, which is obviously good cause we need water, but it also attracts prey animals.
This, of course, was summarized most eloquently at the zenith of human evoloution: the 1982 hit single by Toto clearly stating, “I bless the rains down in Africa.”
You think rain is your ally?
You merely adopted the damp. We Brits were born in it, molded by it. I didn’t see dry sand until I was already a man…
I’m still missing something here. For it to be useful, I’d imagine that it would need to inform decisions, and do so where existing senses would fail.
At least in my environment, if I can smell rain, I could also just as easily use my eyes to see the cumulonimbus clouds and say “rain, due east”.
In the savanna are there scenarios where the only awareness of rain would be smelling it? Can you derive directionality at 5 parts per trillion? Does it matter?
Was that area a desert 250,000 years ago?
Water is life.
Moisture is the essence of wetness and wetness is the essence of beauty”
Victory is life
Maybe an evolutionary trait to locate water?
And thirsty herbivores to eat!
my theory is natural selection of humans/human ancestor species. The ones who didn’t find shelter in time before a rain died/got sick and died later.
I think it’s more than those who couldn’t find water died, within 3 days.
It’s also an off flavor that tasters train for in beer, from water inclusion. It’s not good for beer but I don’t mind the smell at all
Very beet-flavored to me
Funny you should call it beet-flavor. Geosmin is literally the reason why beets have that flavour :)
Yup! I know, I was an expert taster at a large brewery :)
It was fun! And a little bit ruined some beer for me.
You train to taste beer?
Absolutely, if you’re serious about sensory science!
At the large craft brewery I worked in we trained on like… ~40 attributes? Weekly usually, with taste panel and impromptu trainings most every day.
You can study to become a beer judge, even just for fun: dev.bjcp.org/…/beer-judge-training-study-program/
One of the parts of that is to get a kit that helps you recognize “off” flavors: www.bjcp.org/education-training/…/sensory-kits/
I thought it was ozone.
It is also that.
Petrichor is the smell of rain and is a term like Channelle #5 where it’s a combination of ozone and geosmin and other compounds.
Ozone is the smell of an electrical fire
Or poliester fleece or blanket when you hear little sparks.
Some will remember playing with a CRT TV screen 👀
Diff smell.
I call this ‘outside’ smell and you can smell it on a clear day.
There’s also fat volatiles in our skin that metals and sunlight degrade, so that outside smell could be the smell of you in the sun.
I love the smell of redistributed ood in the morning.
Not funny, but interesting!
I fricking love petrichor! Give me that god blood from stone sky daddy!
Wish we could be sensitive to H2S, would have saved a lot of lives.
Make every fart a million times worse.
